EMULSION AND PROCESS O'F MAKING SAME.

No Drawing.

To all whom it may concern:

Be it known that I, LESTER KIRSCHBRAUN, a citizen of the United States, residing in the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Emulsions and .Processes of Making Same, of which the following 18 a specification.

This invention relates to lmprovements 1n emulsions and process of making same and refers more particularly to what may 'be termed a rubber emulsion.

In carrying out this invention, I' may make theemulsion by mixing 20% bentonite or proper colloidal clay, with 80% of rub- I her, which rubber may, if desired, be Para rubber or other well known grades of crude or reclaimed rubber or a mixture of both,

, and also with 60 parts of water. Preferably the water and bentonite will be first mixed and then the rubber added. The rubber can be added in suchform as may be desired. The contents of the receptacle in which this is placed maybe heated to 300 to 400 dogs. F., and the receptacle provided with suitable agitating paddles to thoroughly mix the contents thereof. Also a pressure of from 50 to 200 pounds may be maintained on the contents of the receptacle. This pressure '1113. be obtained from the steam generate or by the introduction of-extraneous gas, which may or may not act upon the rubber, as for example, a hydrocarbon gas. The emulsion so made may be diluted with further addition of water, cooled and Application filed August 16, 1922. Serial No. 582,312.

drawn off. It then may be mixed with fibrous stock if desired and suitably formed. moulded or sheeted. It might be sheeted on a paper machine. The emulsion so formed'is miscible in water. 40 An invention may be carried out in the manner described, to which is added, either with the extraneous gas or otherwise. some suitable reagent, as for example, sulphur. In ordinary operation, this might not benecessary but there might be casesdn which this might be desirable.

I claim as my invention:

1. An emulsion consisting of rubber,

ben'tonite as an emulsifying agent, and a fluid vehicle- I I 2. An emulsion consisting of rubber, an emulsifying agent, and a fluid vehicle.

3. An emulsion consisting of rubber, an

emulsifying agent of an earthy character and water. 4. An emulsion, miscible in water, containing rubber, an emulsifying agent of an ing the same while subjected to the ,action of heat and pressure.
